Abstract
An axle is disclosed having a housing defining a lubricant reservoir. A shaft extends through a bore in the housing and is supported by two bearings within the bore. The shaft has a radially extending surface which partially defines a lubricant chamber for pressurizing and pumping lubricant. The housing has a lubricant passageway in communication with the lubricant chamber. A seal is positioned within the lubricant chamber and has a lip which contacts the radial surface.
